' IMPROVEMENT IN SEED-PLANTERS.

Specification forming part of Letters vPatent No. 96,546, dated November 9, 1869.-

To all whom it may concern Be 1t known that I, JAMES CAMPBELL, of

vented a certain new and useful Improvement panying drawings, vmaking part of this speci- My presentnvention relates to improve- William Campbell the Sthday'of May, 1866, No. 54,642. i

The iirst part of my improvement consists .in making the tread of the ground-wheel of a V form, so as to turn aside or cut any clods in The second part of my improvement consists in making the disk carrying the sets of concentric gears upon the ground or drive wheel, while forming an essential part of said wheel when in place, separable from'the remainder, so as to admit ol' the renewal ofthe gearing without discardingthe whole wheel in The third part of my improvement consists inv extending the cover ot' the seed-box so far back as to form a roof over the exposed part ofthe seeding apparatus and seed-spout.

The fourth part of my improvement consists in the form and position given, to improve its operation,"to the gravita'ting finger or forwarder by which thesuperiiuous grain is pushed back from the seed-cavities when the latter are approaching the discharge aperture, the falling grain being also assisted in its deyscenthy that ofthe forwarder.

The iilth part of my improvement consists in the application ol' a reversible'gage-plato beneath the seed-disk, the saidplate having at its opposite ends truste-conical holes differing from each other in size, and either of which is made to form the discharge-throat oi' the seed-- cavities 5 the said diversity ot' size in the th reatapertures bein g for th'e purpose of making'the same applicable to grains ot va1'i'ous-sizc.

'The sixth part of my improvement consists in an improved combination of devices for adjusting the covering-shares.

Figure 1 is a perspective view of a cornplantcrl'or drill embodying my iu'ventioma portion of the handles andlframe being broken I away. Fig. 2 is mhorizontaliscction through the ground-wheel. Fig. v3 is an enlarged perspective view ot' the reartportiou of the 1 grani-box ork hopper-and its accessories'. *.Fig.-

4 is a vertical section 'of the parts showvnrin "1rg..3. Fig. 5 is avertical section of the parts *I shown inv Fig. 3, taken at right angles to the section shownfin Fig. 4. Fig.:6 iS a pcrsp`ec. tive vlew of the reversible gage-plate. f

The frame has two horizontal beams, 'A B,

'to Whose front ends is'journaled the shaft 01 axle C of the ground or drive wheel.

The shaft 0, at its midlength,carries a disk, D, Vwhich forms vthe central portion of the ground-wheel, the outer annular part .E ot' which is attached to thedisk D by bolts c, f'

which traverse the said annular part, and lugs projectin g radially from the saidfdisk I). The

tread e' oi' the ground or drive wheel is V- formed, (in transverse section,) so as to enable yit to out through 0r turn aside any clods lying in its path'.

The disk has upon its side three concentric gears, d d Ad, with either-ot' which ismade to engage a pinion, F, adjustable upon a shaft,

Gr whoseworm en ages a worm- 'ear-wheel H, upon the lowerend of the vertical shaft'ot' the seed-disk I, which disk forms the-inner bottomof theseed-hopper.v

The back of the' seed-hopper has a recessed part, J, (similar to that shown in my patent aforesaid,) to disclose a portion of vthe seedv disk to the view of thehusbandman, who .is thus enabled to see that the operation is prop erly progressing.

A. curb, I i, serves to prevent the escapeol corn from the edge of4 the seed-disk at itse}c posed part. f.

M is apeculiarly'hent drop-finger or for- Warder, whose oilieer it is to remove any super- "nous grains'from thet'op ot' the secd-czwityjz' before reaching the seed-discharge aperture It ol' the gage-plate K.

',Ihe oiiiee otl the forwarder is also to force f the grain containediil the seed-cavity (i down- ,ward lromthe said cavity, overconnng' any jam that may have taken place owing to the wedging in of two or more grains or from other thefact that the inclination of the operative -raised with equal freedom by either side of the al; "osition that the operating part ofthe for-A w rder shall be'rai'sed vertically from the seedseed-disk; as heretofore.

. entNo, 55h64!! aforesaid, bei'ng arrangedto leither position by a' hook, N,which engages -The gage-plate K` his attachedby a screw',v Q, traversing7 it at its midlength to the basehcleslck is made to t asimilarly-shaped taking' place therein can be readily observed' v the spout, R, and also to the xposed portion Y ofthe seed-disk I and-parts a ]acent.

i .'lheupper part of said cutter is curved-in a line nearly concentric with the wheel, and the lower portion t is curved downwardand back- A ward, so as' to formwhat is" known-as a-jumping-cutter, so; as to dividesmall roots and y 'clods,fand 't'o carry the share' overlarge roots, rock's, or otherxed objects.

Athe seed-hopper isxheldddwm is niade of a cause. The form of the forwarder and divider 'M is shown in Figs; 1, 3, 4, and 5, and is such as to freely allow either a forward or backward rotation of the seed-disk, owing, rst, `to

parts is the same on ,both sides, so as to be cavity i; second, the forwarder is so bent as to allow its pivot-point m to be located in such disk, which is not the case where the pivotpoint is placedmuch` above -the level of the The part m of the forwarder M extends iin a nearly horizontal plane, andis curved in' ward toward thehcpper; the portion m turns downward at an angle of about forty-five degrees with'thehorizontal seed-disk and the portion ml", extends rectangnlarly from 'the portion m"thu`s extending upward `at an angle of about fortyive degrees. f

The seed-box or hopper is hung in a manner precisely 'similar to; that described in' my l-pjat-l `turn on a pivot at'its front, so as to connect or disconnect the wormgear by which the seed- `disk is' operated; the hopper being heldl [in in either of theV holes `oV in the base-plate O of the hopper'.

plateQ, and has at itsends daring holes k k', eitherofwhichin'ay be made to form the throat of the seed-eavity'z, according as the grain `is larger or slnaller, the holes being, as shownin' Flg. 6,"dlvers e iu'size. The duterface of the portions of the gage-plate containing the cavity ,ori countersink'in vthe base-plate, as `showniuFigs.` 4:. and 6. 'lheobjectlof this gage-plate is to l'enable the ready conversion Y `of the corndrillinto a drill for plan'tingany'- f y "other-seed.' l

Thegrain-spout'R is inclined backward, and flared to such an extent that any obstruction bythe operator.. Thal-id S of the seed-hopper .has a backward extension, sf, to form a root to the wide'and backwardly-extending month of "The cutter or colter Tis 'attached tothe' lowerside of the crossbar'U*.o the'frame.

The catch V, by which the cover or lid S of -.ble therefrom, as shown and described, for the'- purpose set forth.

`thinplate 'of spring-steel, tirmlyattached to" the front side of the hopper by its lowerpart, l and its upper part being bent into the reqni` 4site Z form, it"rnakes a Acheap vand eflicient catch. l

The portion of the edge ot' the lid comlngin contact with the catch' ".V -is slightly-curved upward, 'sojas I to improve the action of the catch.l U U are the covering-shares, which have a series of holes, u, to enable their'attachment to the beam by means 'of-bolts Z and holes u for attachment vto the -rear end'ot'- the bracerod W. v v v The fore Iend of the brace-rod `has two or more holes, fw, to receive thebolts Z, by which the brace is attached to the beam,

"The shares incli le backward toward their, lower ends, so as to allow any trashto slide fr ol beneuthjtheir points, and also' to enable d them to ride over lined` objects, such as' roots or stones without breaking thel share or brace.. This inclination of, the shares may be adjusted by means of the holes'vu in the share, or the holes win the brace,`by 'removing the. attachy ing-bolt from' one hole to another. The vertical adjustment of the shares is accomplished d in asimilar manner by means ot' the holes u.

The shares maybe moreor less inclined to the line of draft,to cause them to throw more or less earth,by the insertion of asmallwedge, l X,beneath either edge of theupperend o f'the il t share'and the frame-. i l l V '.lhe beam towhich theshare Ufis attached. has additional boltfholes, a, to allow the setting backward ofboth the share and brace, so as i n to increase' the distance between the shares,. and allow large clods to 'pass between them.- ,The seed-hopper is shown as having but one seed-exit, but it` is. obvious tha'tothers may be addedm'hich may have`discha'rgeinto and be deposited by additional spouts;
